BOX-FORMING MACHINE.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed July-8, 1912. Serial No. 708,287.

To all w/'Lom it may concern:

Be it known that I, MICHAEL QUiNLAN, citizen of the United States,residing at Bristol, in the county of Addison and State of Vermont, haveinvented certain new and useful Improvements in Box-Forming Machines, ofwhich the following is a specification.

My invention relates to box making machinery, and particularly tomachines .for making very small Wooden boxes having notched interlockingends.

One object of my invention is to provide a box making machine of thecharacter above referred to which is relatively simple in construction,posit-ive in its operation and which will automatically assemble boxeshaving a very small cubical content.

Another object is to so construct the box making machinery that it isadjustable within certain limits so that boxes of various sizes may bemade in the same machine.

A further object is to provide means whereby glue may be applied to thetongued ends of the boxes prior to their being moved into position toengage the box sides.

Another object is to provide a machine in which either the sides andends may be assembled without the bottom, or the box assembled with thebottom as desired.

A further object is to provide a mechanism of the character describedwherein provision is made for automatically feeding the end blanks andside blanks into position, automatically feeding if desired the bottominto position, automatically applying glue to the tongued ends of theend blocks, automatically forcing the ends and sides into engagementwith each other, and automatically discharging the completed box.

[in embodiment of my invention is illustrated in the accompanyingdrawings where- Figure 1 is a side elevation of my improved box makingmachine. Fig. 2 is a vertical section on the line 2-2 of Fig. 1. Fig. 3is a plan view partly in section. Fig. 4 is a view partly in section andpartly in elevation of the glue applying mechanism, this view being asection taken on line 4 4 of' Fig. 2. Fig. 5 is a fragmentary section online 545 of Fig. 2. Fig. 6 is a fragmentary perspective view of one endof the machine showing one of the end blank hoppers, the glue applyingmechanism, the feeding device for the end blanks and the hammer forforcing the ends into engagement with the sides. Fig. 7 is a section onthe line 7-7 of Fig 1. Fig. 8 is a perspective View of the slide foroperating the abutment carrying slide and its operat-ing mechanism. Fig.9 is a perspective view of the side blank hoppers and the feeding meanstherefor, this view also showing the means for feeding the bottoms intoposition. Fig. 10 is a fragmentary section on line 10-1() of Fig. 1.Fig. 11 is a perspective view of the abutment, a portion of the devicefor feeding the box botto-m to `the assembling space andthe means forfeeding end blanks to the assembling space. Fig. 12 is a perspectiveview of the ejector and the guideway through which the boxes areejected.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

Referring to Figs. 1, 2 and 3, 2 designates a bed mounted uponsupporting legs, this bed being of open or skeleton formation. The bedis provided with a glue trough 3 which is sunk below the level ofthe bedand is kept warm in any suitable manner.

Disposed upon a slide 4 mounted in guides 15 on the bed at one side ofthe glue trough is one end blank hopper designated 5 and including theparallel spaced side walls 6 and 6a. One of these walls 6'"i is fixedwhile the other, 6, is shiftable to adjust it toward or from theoppositev wall 6a. To this end, the wall 6 has a base flange 7 which istransversely slotted at a plurality of points as at 8, and into theseslots pass screws or bolts 9. By loosening these screws, it is obviousthat the wall 6 may be shifted toward or away from the wall 6a and thatby tightening the screws, the wall may be held in its adjusted position.The hopper 5 is open at one end and at the other end is closed by an endpiece 10 through which passes a feed plunger 11. It will be noted thatthe end piece 10 is sufficiently long to close the end of the hopper forany adjustment of the wall 6. The plunger 11 passes through a yoke 12.Contractile springs or like devices 13 are connected to the end of theplunger and at their inner ends are attached to any fixed support as forinst-ance the pins 14 projecting from the side walls of the hopper 5 asshown most clearly in Fig. 6. Supported between the side walls of thehopper are the end blanks A. The bed 2 is formed with lateral undercutguides 15 between which the slide 4 slides so as to be adjustable tothereby accommodate boxes of greater or less length. It will beunderstood, of course, that the glue trough 3 is of a length equal tothat of the largest box made by the machine.

Disposed upon the opposite margin of the glue trough or pan 3 is the endblank hopper 16, composed of the spaced side walls 17 and 17a. Thishopper is constructed in precisely the same manner as the hopper 5 butneed not be adjustable toward or away from the hopper 5, though it maybe so made. The wall 17 is, however, adjustable toward or from the wall17a, it being provided to this end with the base flange formed withslots 18 through which pass screws 19. The end of the hopper is closedby an end piece 20 and carrying a yoke 21 and through this yoke passes afeeding plunger 22 which presses against the end blanks A. The plungeris forced inward by means of the contractile springs 23 attached toprojecting pins 24.

Extending outwardly from the hopper 5 is a vertical wall 25 upon whichis mounted the oppositely disposed horizontally arranged guides 26forming a guideway between which the feeding plunger of the end blankhopper 5 moves.

Preferably and as illustrated, the guides 26 are mounted upon and formedintegral with a plate 27, and preferably and in order to verticallyadjust the guideway formed by the plate 27 and the guides 26, thevertical wall 25 is vertically slotted as at 28, and screws or bolts 29pass through these slots. As illustrated in Fig. 6, the face of the wall25 is cut out so as to form a recess 30 within which the guide plate 27shifts. By forming the wall 25 with the recess 30, the feed plunger orpush rod may always be supported so as to engage the middle of the endblank, no matter what its height may be. Slidingly mounted between theguides 26 and in said guideway is a reciprocating feed plunger 31 orpush rod which is illustrated particularly well in Fig. 6. This feedplunger carries at its extremity a spring finger 32 which is attached tothe face of the plunger and extends slightly outwardv or away from theface of the guideway and is provided with inwardly projecting terminalears 33. When the feed plunger 31 is moved toward the hopper 5, theseterminal ears which are rounded at their edges ride up over the firstend blank of the series contained within the hopper 5 so that theterminal ears press against the middle of the block and at the same timethe inner end of the plunger 31 engages the edge of the first end blockof the series and as the plunger reciprccates, this end block is shiftedover as shown in Fig. 3 in dott-ed lines to the position where the boxis to be formed.

As illustrated in Fig. 6, the wall 25 at its inner end is upwardlyextended as at 34, and immediately above the opening of the hopper 5there is disposed an outwardly projecting hub 35 which is formed with avertical guideway 36. Disposed in this guideway is an angular finger 37.The body of this finger is longitudinally slotted while the lower endthereof is angularly bent as at 38, this angularly bent end striking thefirst block of the series slightly above its middle asl illustrated inFig. 4. A screw 39 passes through the slot in the finger and extendsinto the hub so that the finger as a whole may be vertically adjustedwith relation to the opening of the hopper 5.

Projecting from the plate 37 below the slot thereof is a screw 40, andmounted upon this screw is an angular plate or finger 41 which isvertically slotted for the passage of the screw 40 andl which has aninwardly extending terminal end which engages the face of the block Abelow its middle. It will thus be seen that the first block A of theseries of end blocks or blanks contained within the hopper 5 is forcedinto contact with the angular terminal ends of the fingers 37 and 41, asillustrated in Fig. 4, and that the end blanks A are held firmly betweenthe plunger 11 and these angular terminal ends of the fingers. Thesefingers do not project in so far as to interfere with the movement. ofthe plunger 31 and the spring finger 32 passes between the angularterminal ends of the members 37 and 41.

The base upon which the hopper 5 and the wall 25 are mounted is formedwith a ledge or track designated 42 which extends across the front ofthe hopper with its upper edge in line with the bottom of the hopper,and this ledge as shown in Fig. 6 supports the end blank from the timeit is forced into engagement with the angular ends of the members 37 and41 until it is forced into position to form the box as will be hereafterdescribed.

Mounted upon the flange 7 is a guide for the end blank, preferably madeof wire. This guide comprises a looped base 43 through which a set screw9a passes. The base then extends upward, then toward the front of thehopper, then outward parallel to the line of travel of the end blank,then upward and downward in the form of an arch as at 44 (see Fig. 6)toward the glue trough as at 45, the extremity being outwardly inclinedso as to readily receive the end blank and to guide the same in itscourse past the space between the inner wall 6 of the hopper and thehammer 46 to be later described.

Mounted upon the hammer 46 is a guiding spring 47. The hammer 46 isprovided with the upwardly projecting post 48, and projecting throughthis post is a screw or bolt 49. The spring linger 47 is angular in formand the upper end thereof is vertically slotted to receive the bolt 49.The lower end of this slotted portion extends down ward to a level withthe upper edge of the end blank A and is then liattened and downwardlybowed as at 50 so as to press gently upon the upper edge of the endblank as it travels from the mouth of the hopper to the position shownin Fig. 6. During all this period, the spring linger holds the blank inposition, and when the blank reaches the position shown in Fig. 6, thespring linger 3Q holds it lirmly against the end of the hammer block 46.lhen it has reached the position shown in Fig. (3, the end blank is inposition to be assembled with the side blanks as will be laterdescribed.

The mechanism for feeding the end blanks from the hopper 1G is preciselythe same as that describetil for the hopper 5. Projecting upwardly fromthe bed is a vertical wall 51 which corresponds to the vertical wallpreviously described, and mounted upon this wall is the guideway 52which is precisely the same construction as the guideway 2T previouslydescribed. ,Sliding laterally in this guideway is the plunger rod 53which acts to urge the blanks contained within the hopper 16 intoposition where they may be assembled with the side blanks. This plungerrod like the plunger rod 8l is provided with the spring linger andhaving the inwardly turned ears The wall 51 is upwardly extending as at5G and is formed with the central thickened hub 57 corresponding to thehub This hub is formed with a vertical guideway in which is adjustablydisposed the linger 58, being held in place by the screw 5S). The lowerend of this linger is angularly bent as at (i0, and mounted upon thelinger 5S is an angular linger (il corresponding to the linger 41previously described. The end blanksl are held in position between theplunger 22 and the spring lingers and in position so as io be engaged bythe inner end of the plunger rod as the latter slides across the face ofthe hopper 1G. The blank is supported upon a projecting ledge 56corresponding to the ledge and the blank is guided by means of thearched guide 57 which corresponds in every particular with the archedguide 44.

It. will be noted from Fig. 3 that while the hoppcrs for the end blanksare similar in construction and the actuating mechanism therefor is thesame for both hoppers, yet the position of the hoppers is different andthat the hopper 16, for instance, is set nearer to the side of themachine than the hopper 5 and that the glue trough 3 is offset at oneend. The reason for thus placing the hopers out of aiinement with eachother is that the end blanks A are to be applied last of all while theend blanks A are the first blanks to be moved into position.

Both the end blanks A and A are formed with tongues so as to interengagewith tongues upon the side blanks B and B. It is desirable that theinner faces of the end blanks, and particularly the inner faces of thetongues, be wiped with glue or like adhesive before they are moved intoposition, and to this end I have provided glue applying mechanism whichis shown particularly in Figs. 4 and Both of these glue applyingmechanisms are alike and a description of one will suffice for theother. Taking, therefore, the glue applying mechanism for the hopper (i,it will be seen that projecting upward from the enlargement 34 of thewall 25 there is a grooved standard forming a guide and designated (32.Mounted in this vertical guide (3Q is a reciprocating slide rod (33having projecting from it an apertured lug 64 thrrnigh which passes atransverse shaft G5. Mounted upon the ends of the shaft are the sleeves6o having downwardly and outwardly projecting socketed arms 6T.Extending downward from these arms are the wires GS forming extensionsof the arms. These wires extend downward and out vard for a distance andthen extend vertically downward and at their ends carry glue brushes (39which normally dip into the glue trough 3 and which are so spaced apartthat when the slide (33 is raised, the glue brushes wipe against theside margins of the blank lt will be seen that the sleeves GG may belaterally adjusted upon the shaft G5 so as to space the glue brushesapart from cach other the required dista nce for any sized end blankswithin the limits ofthe machine. and further it will be seen that thewires G8 are supported in sockets (37 and are adjustable in thesesockets by moans of set screws. The means for reciprocating the slidingrod (1?) will be later described together vith means for reciprocatingthe plungers for feeding the end blanks from their hoppers.

The box is formed in line with the hammer 46 as illustrated in Fig. 2land disposed on one side of the space (il within which the box is formedis a sliding abutment 70, the particular function and construction ofwhich will be later described. Opposed to the abutment 7() are certainguides which will also be later described. the two sides B and B of thebox (see Fig. 3) being shoved into place between these guide stops andthe abutments. Extending from one end of the machine to the space Cwithin which the box is formed, is a guideway designated 71. Thisguideway is formed by laterally disposed walls 72 and 73 (sce Fig. 10)which are formed with longitudinally extending dovetailed grooves 74upon the inner faces. The lower faces of these walls 72 and 73 arerabbeted as at 75. The wall 72 is fixed relative to the bed of themachine but the wall 73 is laterally adjustable, this wall beingprovided with outwardly projecting slotted lugs 76 as illustrated inFig. 9 through which pass binding screws 77. The guideway is thusadjustable so as to acconnnodate it to various widths of boxes. Thewalls 72 and 73 are mounted upon a sliding plate 78 and this plate inturn is slidingly mounted upon the bed 4. This bed -1 is slotted as at79 for the passage of a feeding chain for the bottoms.

Disposed at the inner ends of the walls 72 and 73 are the hoppers 80 and31 to receive the side blanks B and B. These blanks are formed withtongues at their ends. The blanks are arranged so as to extend parallelto the walls 72 and 73. The hoppers are formed each by the side walls 82and 83. These side walls are angular in cross section. Each wall 82 isfixedly mounted upon the slide plate 78 and each wall 83 is adjustablymounted, the base of the. vall being laterally slotted as at 84 andhaving set screws 85 passing down through the slots. It will be notedfrom Fig. 9 that there are two of these hoppers 80 and S1, and that theyare arranged on each side of the guideway 71. The side blanks B and Bare fed into the guideway by means of plungers 8G which pass throughguides 87. The outer end of each plunger is connected by contractilesprings 88 to eyes S9 carried by the side walls 82 and S3 so that theblanks contained within each hopper 80 or S1 are fed forward by thepressure of these contractile springs.

Engaging the grooved walls 72 and 73 of the track 7l are feed rods 90.Each rod has a dovetailed rib extending partly along its length whichengages with the dovetailed groove 72. These feed rods 90 arereciprocated by mechanism which will be hereafter described. Yhen thefeed rods move back so that the inner ends of the ribs aline with thewalls S2 of the hoppers 80 and 81, the plungers 8G will force the sideblanks into the guideway 71. Then as the feed rods 90 move inward, theribs on the feed rods will engage the outer ends of these side blanksand push them inward along the guideway and into position in theassembling space C. It will be understood that inasmuch as each feed rod90 extends beyond the inner end of the rib, this projecting portion ofthe feed rod acts as a stop to prevent the outward movement of the sideblanks beyond the tracks upon which the side blanks move. The feed rodsnever move so far outward as to permit the ends of the feed rods beyondthe ribs escaping the open ends of the hoppers.

Passing along the slot 79 and a slot 79:t in the sliding plate 78 is asprocket chain 91. This sprocket chain passes over sprocket wheels 92and 93, the sprocket wheel 92 being mounted upon the outer end of thesliding plate 78 while the sprocket chain 93 is mounted at the inner endof the guidewa as illustrated in dotted lines in Fig. This sprocketchain carries projecting from it the paddles or studs 91. As illustratedthere are three of these paddles or studs adapted to engage with bottomblanks which are fed into the guideway between the reciprocating feedrods 90. The means for actuating the sprocket chain will be laterdescribed.

The two walls 32 and S3 forming the hopper 31 and the wall 73 of theguideway 71 are all mounted upon a sliding plate 95 adapted to slidelaterally in guides 9G mounted upon the bed plate of the machine.Extending parallel to the direction of movement of the feed rod orplunger 31 and attached to the bed of the machine is a guide strip 97which also coacts with the guide strip 90 and disposed between these twoguide strips 90 and 97 is a slide 98 carrying upon it an upwardlyextending adjustable wall 70. This wall is adjustable laterally withrelation to the slide 9S, and to this end is mounted as shown in Fig. 1lin laterally extending guide strips 99 mounted upon the plate 98. Theseguide strips form a dovetailed slideway and the bottom of the member ofthe block 70 is formed with a dovetailed tongue 100 which engages inthis dovctailed slideway. This permits the block 70 to be slidlaterally. The inner face of the block 70 is vertical and smooth faced,and when the slide 98 is in one position, the inner face of the blockforms a wall against which the side blank B is carried. The block 70 isprovided n ar its bottom and just above the guide strip 99 with aprojecting ledge 101 adapted to support the side blank as the side blankis shifted into position.

On the opposite side of the assembling space C are arranged theadjustable supports 102, 103 and 101. The support 102 consists of a pinhaving an enlarged base, the enlarged base forming a shoulder. This pinis shiftable into a plurality of perforations 105 formed in the bed ofthe machine. The support 103 projects upward and has nar its base on itsinside face a ledge 10G at the same height as the ledge formed on thepin 102, and the support 101 is made in precisely the same manner as thesupport 103 and is formed with a ledge 107. These three ledges areintended to support one of the box sides as it is moved into position.The pin 102 may be adjusted into one or the other of the perforations105 to accommodate boxes of a larger or smaller size. The support 103 isupwardly extended as at 108 and passing therethrough is a clamp screwwhich engages in the slotted body 109 of a linger having an angularlyturned end 110, which is adapted to press down upon the top edge of thebox side as it is shifted into position. The block 70 is also providedwith a Alinger for engaging the upper edge of the box sidesupported'against the face of the block 70. To this end the block T0 isupwardly extended as at 111 and through this extension passes a clampscrew 112. The linger 113 is horizontally disposed in ythe line oftravel of the box side and is angularly beni and upwardly extended as at114 and formed with a slot through which the clamp screw 112 passes. Itwill be seen that these fingers may be adjusted up or down so as topress with greater or less force against the upper edges of the boxlsides.

Projecting from the end of the slide 93 is a box support comprising anoutwardly projecting arm of wire designated 115 having au upwardlyturned terminal end. This wire arm extends upward and outward. As amean-1 of limiting the inward movement of the slide 93, l form the bedplate with a series of perforations 11G (see Fig. 2) and provide a pin11T which engages in any one of the-e perforalions and forms a stoplimiting the inward movement of the slide 9S. The slide 93 reciprocateswithin its guides and the means for moving this slide will be describedlater.

Disposed between the wall S3 of the hopper 80 and the support 103 is asliding block designated 11,8 and illustrated in Fig. 8 in detail. Thissliding block is connected to a slide plate or strip 119 moving inguides mounted upon the bowed plate. This slide plate or strip 119extends transversely of the line of movement of the side blocks. Theblock 11S in its normal position is in alinemeut with the inner face ofthe support 103 but it may be, shifted from this position to theposition shown in Fig. 3 where the active face of the block is in linewith the inside face of the block 70 and closes the end of the boxforming space C. This block 118 has a llat vertical tare 120 againstwhich the end bleek .Y bears when the two end blanks and the side blanksare placed in position. The block 115l carries upon it the upwardlyprojecting lug 121 carrying the angular linger 122 which adapted to bearupon the end blank and support the end blank.

It will be noted that the side walls 82 and S3 terminate short of theslot in the plate T3 so that a ledge 123 is left over which the tongues71 move, which ledges form tracks for the side pieces. Beyond the sidewall 33 of lthe hopper 81 there is a guiding spring 125 (see Fig. thisbeing yieldable so as to permit the block 118 te shift into the positionshown in Fig. 3. Normally the block 118 occupies a retracted positionopposite the spring 125 and spaced therefrom the width of the passagewaythrough which the side blanks travel.

The block 11S as illustrated in Fig. 8 is formed on its lower marginwith a projecting ledge or track 120 to support the side blank as it isshifted toward the box forming or assembling space. This ledge 120 isformed by a strip received in a recess 12T on the under face of theblock and resiliently forced outward by springs 12S as illustrated inFig. 8. The reason for making the strip 120 yielding is to permit theblock 118 to be shifted up closely against the face of the block in theposition shown in Fig. 3. The slide 119 is connected in any suitablemanner to the operating mechanism as will be later described, and it maybe merely stated here that the slide is provided with an upwardlyprojecting lug 129 which extends up through a slot 130 formed in thesliding plate 95.

Assuming that the box is formed in the manner as will be describedlater, it is necessary that the complete box should be shifted into suchposition that it may be discharged. It is for this reason that the plate93 slides laterally carrying the completed box resting upon the ledge111 and supported between this ledge 111 and the spring finger 113. Theoutwardly shifting block T0 carriesl the box with it until the boxarrives opposite a discharge channel 131 (see Figs. 3 aud 12). Thisdischarge channel is formed by two spaced walls 132 and 133 mounted uponthe slide 1. The wall 133 is fixed. on this sliding plate` while thewall 132 is adjustable toward or from the wall 133 and to this end isformed with an angular slotted base through which pass clamp screws 131Vas clearly illustrated in Fig. 12. ly this means the discharge channelmay be narrowed or widened in order to suit various widths of boxes.

The plate -1 is adapted to be adjusted toward or from they middle of themachine by means of an adjustingF screw 135 passing through a lug` 130formed upon the table or bed, the adjusting screw being provided with ahandle. Any suitable means, howev r, may be used for adjusting thisslide 4 toward or from the center of the machine. lt will be seen thatthe slide carries with it tie hopper 5, the feeding means for said hepper, the glue applying means therefor, the hammer 410 and the dischargechannel 131.

The hammer 1G is illustrated in detail in Fig. G. As shown in thisfigure, the plate 42 has laterally disposed guides thereon designated137 and mounted in these guides is the hammer 10 which is provided atits base with the downwardly and outwardly projecting tongues 133. Theguides 137 are connected at their rear ends as at 139 and projectingupward therefrom is a lug 140 through which passes a stop pin 141 whichlimits the rearward movement of the hammer. rthe hammer has a slidingmovement toward and from the box assembling space.

lefore describing the mechanism whereby the various movements necessaryare secured. it may be well to describe the general operation of forminga box in accorolance with in v invention.

The hoppers 5 and 1G are filled with nnd blanks disposed as shown inFig. 3 and the hoppers S0 and S1 are filled with side blanks disposed asshown in Fig. 9. The first movement of the machine is to shift the firstend blank of the series from the hopper 5 laterally in the direction ofthe arrow in Fig. 3 to the end of the box forn'ling space C where it issupported against the hammer and by means of the linger 50 in theposition shown in Fig. o. A\t the same time that this is occurring. thepush rods 90 are moving inward and the tongues on these rods engage thefirst side blanks B and B of the series and force them forward along theguideway 71. .\s these blanks are forced forward they come into positionshown in Fig. 3, that is. on each side of the space C. As soon as theside blanks have moved into the position shown in Fig. 3. the second endblank is shifted inward from the position immediately in front of themouth of the hopper 1G to thc position shown in Fig. 3 at the end of thebox forming space. At the same time that the end shifts over from themouth of the hopper 1G to the end of the box forming space, the abutmentblock 118 also shifts and occupies the position shown in Fig. 3. Thefour pieces from which the box is formed are now in position. If thebottom is not to be applied to the box at this time, the hammer is nowforced home which forces the tongued end pieces into engagement with thetongues at the ends of the side pieces and the box is completely formed.If the bottom is to be applied to the box. then before the second endpiece A is shifted into the position shown in Fig. the tappet 94 on thechain 1 moving along the guideway will carry with it a box bottom D.

lt will be understood that the hopper bote toms are to be fed by hand tothe chain 91. In otheY words, the hopper bottoms are inserted one by oneon the chain and carried forward between the members 90, the members 90therefore acting as guides. The tappet Slt of course engages the bottomand the bottrian is `o'ra dually fed into position by the chain. l donot. of course. wish to be limited to feeding` the box bottoms intoplace by hand as automatic means might be used for this purpose.

After the box is con'ipletely formed and the hammer is operated so as tolock the parts in their connected position, the block TO slides over asbefore described so as to carry the box to the entrance of the deliverychannel 131 and the box is swept out along the delivery channel as willbe later described. s soon as this occurs, the slide 98 moves so as tocarry the block back to the position shown in Fig. 3 and at the sametime the abutment 118 is carried back so that its face is in alinementwith the face of the supporting members 103 and 104, thus leaving theway clear for a new box to be fed.

Power is applied to the machine by means of a power shaft designated1st-2 as shown in Fig. 1. this shaft carrying upon it a power wheel towhich power is applied by means of a belt or in an)Y other suitablemanner. The shaft extends longitudinally under the machine and in orderto drive the endless sprocket chain 91. the shaft 1-12 is provided nearits extremity with a worm gear 11?) which engages with z gear wheel 141carried upon a shaft 115 which in turn supports the sprocket wheel 92.Thus a continuous rotation in one direction communicated to the sprocketwheel 92 and from the sprocket wheel 92, of course, to the sprocketwheel 93.

Projecting upward from the tables are the upwardly extending brackets orstandards l-rtt and 11T journaled in which is the shaft 148 whichconstitutes the shaft whereb v nearl',v all of the motions communicatedto various parts of the machine are secured. This shaft 11S as seen inFig. 0 carries upon it the eccentric lit) over which passes an eccentricband 150. Projecting downward from this band is the eccentric rod` 151which is offset at its lower end and has a vertically slotted head 152disposed immediately over the slot in the rear end of the hammer 16.

Pivotally mounted upon a fixed support 153 is one lilik 171i of atoggle. The end of this link 154 is longitudinally slotted. Pivotallymounted in the bifurcated rear end of the hammer 4G is a link 155. theupper end of this link being perforated for the passage of a bolt 15Gwhich passes through the slot in the end of the arln 15st, passesthrough the perforation in the end of the arm 155 and into the slot inthe head 152. By means of the longitudinal slot in the head the amountof throw of the hammer 4G may be adjusted. 3y means of the stop 111 therearward morement of the hammer may be limited. lt will be seen thatupon a rotation of the shaft 14S a reciprocating motion will be given tothe hammer block 146 so to throw it backward and forward toward and fromthe track or guideway over which the end blank A passes. The shaft 14Scarries` upon it a crank 15T as shown in Figs l, Q and G.

Mounted upon the upper end of the standard 146 is a laterally extendingbracket 158 formed in two sections adjustable upon each other so as toshorten or lengthen the bracket. The bracket extends at right angles tothe shaft 148 and then extends longitudinally parallel to the shatt 148for a distance slightly beyond the position of the eccentrics 1-19 as at159. The bracket as this point is formed with a bearing for the end ofshaft 16-1 extending longitudinally parallel to said shaft andprojecting from the base of section 159 is an arm 160 formed at its endwith a slotted head 161 constituting a support for a sliding rod 176.The bracket 158 is preferably made in two sections, one ot the sectionsbeing formed with slots 162 while the other section has set screws 168passing through said slots so that the bracket section 159 may beadjusted. The extremity ot the section portion 159 of the bracket 158 asbefore stated. carries a bearing to support the end ot shaft 16-t. Thisshaft extends longitudinally and parallel to shaft 148. Mounted uponthis shaft 164- is a lever 165 formed in two sections, one end ot' oneof the sections being formed with a slotted yoke 166. The crank pin 167of. the crank 157 passes through the slot of this yoke. It will beobvious, therefore, that as the shaft 148 is rotated, the crank willcause a rocking movement of the lever 165. As before stated` this leveris made in two sections, one of said sections being formed with a slot168 while the other section is provided with a pin 169 which passesthrough the slot and holds the lever 165 in any adjusted position. Thislever 165 is connected by means et' a link 170 to the upper end of thereciprocating bar 68. 1t will therefore be obvious that as the lever 163is reciprocated, the bar 168 will be reciprocated and thus the gluewipers or brushes 69 will be wiped against the tongued ends of the endpieces .1. This shat't` 161 also carries upon it the crank 171 whosecrank pin engages in a slotted yoke 179 formed on the end of a likelever 173 pivotally mounted upon the shaft 164. This lever 172 isconnected by means of a link 174 to the upper end of the reciprocatingbar 63 which reciprocates the glue brushes or wipers for the hopper A.

Mounted upon the shaft 1-18 is a cam 175 for actuating the pushers whichjfeed the end blanks A out of the hopper 6. Mounted upon the extremityof the arm 161 is a sliding rod 176 which slides through an opening inthe end of the arm 161 and which carries at its inner end a roller 177which engages with the face ot the cam 175. The other end of the rod ispivotally connected to a lever 178 which extends downward and outwardand is formed at its lower end with a slotted yoke 179 which engagesover a screw pin 18() projecting from the plunger 31 (see Fig. 2). Thislever 178 is formed in two sections, one of said sections being slottedas at 181 and the other section being provided with adjusting screws 182which engage in said slots so that the lever may be adjusted for length.The rod 176 is also formed in two parts, one ot said parts being slottedas at 188 while the other part is provided with a pin 18-1 whereby therod `may be held in its lengthened or shortened condition.

It will be secu that the rotation of the shaft 148 will euse a rotationof the cam 175 and that this in turn will wipe against the rollei` 177and cause the rod 176 to reciprocate, thus oscillating the lever 178 andreciprocating the sliding plunger 81, thus feeding the end blanks A oneby one into position at the end of the box forming space C.

The mechanism for operating the sliding plunger 58 is the same as thatfor the plunger 81. The standard 185 is provided with the arm 186 whichis provided with a slotted head 187 corresponding to the slotted headatthe end of the arm 160. Mounted upon the shaft 148 is a cam 189 whichwipes against a roller carried upon the end of a rod 190 which rod ispivotally connected to ay lever 191 corresponding in every respect tothe lever 178 which at its lower end is pivotally connected to the slide53. The cams 175 and 189 are so set relatively to each other that thecam 175 operates before the cam 189 and thus the movement of the endblank A is retarded behind the movement of the end blank A.

For the purpose of shitting the abutment 118, I provide a cam 192mounted upon the shaft 148 and engaging with the bell crank lever 198pivoted upon an adjustable bracket 194 projecting outward from thestandard 185. This bracket 194 is vertically movable upon the standard185. The bell crank levc at its upper end carries a roller 195 whichbears against the cam 192 and the lower arm ot the bell crank lever hasa slotted yoke 196 which engages with a pin 197 projecting upward fromthe lug 129 upon the slide 119. 1t will be seen that as the shaft 148rotates, the bell crank lever will be oscillated and this in turn willgive a reeiprocation to the slide 119 and the abutment 118, the lengthof travel of the slide being sutlicient to carry the abutment from theposition shown in Fig. 8 to a position where its inner face is inalinemcnt with the working face of the support 103.

For the purpose of reciprocating the feed rods 90. 1 provide a cani 198having a cani track 199 in its periphery. Mounted upon the standard 147at the end of the machine is a bracket Q00, this bracket carrying atransversely extending supporting member Q01 upon which a lever 202 ispivoted. The upper end of this lever is formed with a lonturn the partsto their original position.

gitudinally slotted head 203, and mounted upon the bracket 200 is alever 204, the inner arm of which is upwardly curved and then extendedinto engagement with the cam groove 199. The other end of the arm asbefore stated projects into the slotted head 203 so that as the camrotates, the lever 204 will be reciprocated and the lever 202reciprocated. The lower end of the lever 202 is formed with alongitudinally slotted head 205 which engages with a plate 20Gadjustably mounted upon the feed plungers or slide rods 90. This plateis rigidly attached to one of the slide bars but is transversely slottedas at 207. Clamp screws 208 extend through these slots and into theopposite slide rod or plunger. It will thus be seen that one of theslide rods may be adjusted relatively to the other so as to accommodateboxes of different widths within certain limits. The plate 20G is formedwith an upwardly projecting lug 209 which has a pin engaging in theslotted end of the lever 202.

The means for shifting the wall is as follows. Mounted upon the shortlongitudinal shaft 142 is a segment gear 211 which meshes with a rackbar 212. This rack bar is connected to the slide 98 as illustrated inFig. 2. The rack bar operates against the force of the spring 213. Asthe shaft rotates, the segment 211 will engage the rack, will shift therack in one direction, and as soon as the segment gear releases itsengagement with the rack, the spring 213 will riet will thus be seenthat the block 70 will be reciprocated and shifted from the positionshown in Fig. 3 to a position where the acting face of the block isparallel with the wall 132 so as to permit the formed box to belaterally shifted into the discharge passage 131.

The means for shifting the box into the discharge passage and along thesame is illustrated in Figs. 1 and 12. Mounted upon the shaft 148 is acam 214 formed with a cam track 215 in its face. Projecting out from thestandard 146 is a bracket arm 216, and mounted upon a downwardlyprojecting member 217 extending from this bracket is a lever 218. Theupper end of this lever is formed with a slotted head 219`r and mountedupon the extremity of the bracket arm 216 is a lever 220, one end ofwhich projects into the slot of the upper end of the arm 218 and theother end of the lever engages in the cam track 215. By this means itwill be Seen that as the shaft 148 is rotated. the lever 218 will beoseillated and that the lower end of the lever will swing in thedirection of the discharge passage between the walls 132 and 133.

1t will be noted from Fig. 1 that the lever 218 is not so long as toextend down very far into the passage when the lever is in its normalposition. lVhen the lever is oscillated, however, the lower end, whichis relatively wide as illustrated in Fig. 12, engages with the rear endof the box and the box is moved forward into the discharge passage. Itwill be seen that each box as it is made is forced into this dischargepassage and that the entire row of boxes contained between the walls 132and 133 are shifted until the boxes drop out at the end of the passage.

The general operation of the invention is as follows. The shaft 148 isof course driven from the main driven shaft. As the shaft rotates, thecrank 216 will first act to reciprocate the glue brushes so as to coverthe ends of the end blank A with glue. As soon as this has happened, thecam 175 will operate to actuate the lever 178 and push the end blankinto the position shown in Fig. 6, that is, immediately opposit-e theend of the space C where the box is formed and against the inner end ofthe hammer 40. Meanwhile, the caln 198 will operate to shift the lever202 and shift the slide rods 90 longitudinally so that each slide rodwill engage one of the side blanks B and B and shift them into positionone against the block 70 and the other against the supports 102, 103 and104. If the bottoni of the box is to be put on, a bottom is fed to theendless chain 91 and the paddle 94 will engage the bottoln, shift itlongitudinally and slip it into place between the two side blanks, theedges of the bottom fitting the grooves in the side blanks, As soon asthe sides and bottom are in place, the cam 18) operates to shift the endblank A across the machine and into the position shown in Fig. 3. Thefour sides of the box are now ready for assembling and as soon as thisis accomplished, the eccentric 149 operates and the hammer 4G is drivenquickly against the end of the box so that the box blanks are compressedbetween the hammer and the abutment 118 which is moved over with the endblank A. This stroke of the hammer is of great importance as it finallyfinishes the box and forces the parts into thoroughly close interlockingengagement. As soon as this has been accomplished, the bloclc 70 shiftslaterally by reason of the engagement of the segment gear with the rackand inasmuch as the box is supported between the ledge 101 and the inger113, the box will be carried outwardly with the blocks 70. Then theblock 70 reaches a position so that its inside fiat face is parallel tothe inner face of the wall 132, the cam 214 will actuate the ejectorlever 218 which will force the box outward into the discharge passage.As soon as this occurs, the member 70 will be shifted back intoposition, the button 118 will also move into its original position andthe parts lvill be ready for the formation of a new It is to beparticularly noted that all the parts are adjustable within certainlimits so that various sizes of small boxes may be readily made withincertain limits,
